    Clipsal Wiser for C-Bus Automation Controller (5500SHAC) has RTU and TCP modbus capabilities but AFAIK there is no direct C-Bus to Modbus converter.

    Depending on what you need to do and how complicated it is there is no reason you could not do it in the logic engine - if you are only writing say a few coils or registers you could hard code them into the logic

    I MICK

    this is the problem
    i have a modbus master

    I have to be able to read but above all write some registers belonging to devices that communicate in c-bus

    but this is the point

    the idea is to be able to directly manage the c-bus controller on a modbus network

    ie master modbus -converter - c-bus controller - devices

    there is a converter capable of doing so

    I don't think there is something that can do it directly between Cbus and Modbus.

    However, Cytech just released a UCM/Modbus to interface with their alarm system. If you have a UCM/Cbus then there might be a way to use it between Cbus and Modbus with certain limitations. The UCM/Modbus only works with signed integers so anything larger would require clever programming or won't work at all.

    HI INGO

    I understand that there is no conversion in a single solution

    but it's possible to a c-bus converter to bacnet and then bacnet to modbus converter

    you know c-bus converters to backnet

    thanks for every reply

    This is an old thread, but could this now be done with a Raspberry Pi?

    SHAC does this stuff via it’s built in process, it’s not particularly tough, my client is an A/C engineer he did that bit and I built his cbus setup.

    what is the cost of a SHAC? Probably more than its worth just for MODBUS

    Are you looking to control a MODBUS device Mick, or looking to control C-Bus from a MODBUS master?
